APPARATUS FOR VENDING GAS.

SPECIFICATION forming part of Letters Patent No. 405,943, dated June 25, 18.89.

Application iiled June 12, 1888. Serial No. 276,846. (No model.) Patented in England May 18, 1887, No. 7,012: in France March 5, 1888, No. 176,142, and March 8, 1888, No. 176,220, and in Germany March 12, 1888, Nos. 22,737 and 22,738, and March 2o, 188s, No. 23,292.

To @ZZ whom it may concern:

Be it known that I, Ron/*LAND WILLIAM BROWNHILL, engineer, a subject of the Queen of Great Britain, residing at 111.1? High Street, Aston New Town, Birmingham, in the county ot Varwick, England, have invented a certain new and useful Apparatus for Vending Gas, (for which applications for Letters Patent have been made as follows: Great Britain May 13,1887, No. 7,012; France March 5, 1888, initial No. 176,142, and March 8, 1888, initial No. 176,220; Germany March 12, 1888, initial No. R. 1.3.22,787, March 12, 1888, initial No. R. P. 22,738, and March 20, 1888, initial No. R. P. 23,2925) and Ido hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

The invention relates to an apparatus for vending gas in a determinate quantity on the same having been previously paid for by depositing a coin or coins within a receptacle or through a slit made in the inclosing-t'raming of the said automatic means. Thus the vending means, in connection with a gas-meter, consists, essentially, of a coin-lever which is operated by a coin or coins pushed or introduced into the apparatus in prepayment for gas to be supplied, and which lever through links or the like gives a proportionate or partial backward movement to a disk or disks having inclined notches cut within their peripheries, wherein a catch or cross-bai` lies when the meter is at rest. The other parts consist, essentially, of trains ol wheel-work which are driven directlyfrom the drum ot the meter and through some of them communicate the necessary backward movements to the disks, which are the gas-measuring-ont disks.

Figure 1 represents in front elevation, with some ot the parts broken oil", and in vertical section a portion of a gas-meter provided with automatic sale, delivery, and check mechanism, constructed and arranged according to my invention, and the parts of which said mechanism are shown in the positions which they assume on a penny being iirst tendered in payment for a predetermined quantity ot gas required to be delivered. It will be seen by the sa'idFig. 1 that the coin, which is marked c, has been dropped through the coin-slit and is restingbetween the grooved peripheries of two pulleys disposed at a distance apart. Fig. 2 represents a like elevation and section as that of Fig. l, but with the parts of the said automatic sale and delivery check mechanism in the positions which they respectively assume after the coin has been forced partially between the grooved pulleys, as hereinafter described, and which said opening' out of the pulleys to the extent of the coins diameter is the limit of movement which the said parts make. Fig. 3 shows a like view as that of Figs. 1 and 2,but with the respective parts ot the automatic sale and delivery mechanism in the positions which they assume after the coin tendered in prepayment of gas to be supplied has passed through thc machine and been conveyed into a receptacle made t0 receive it. It will be observed that the machine is now delivering out by the back rotation of gas-measuring-out wheels, and that the mechanism only commences to deliver or act after the coin has been fully passed through the machine. Fig. 1 is a plan view, partly in section, of the said mechanism and inclosing-casing upon the dotted lines A B, Fig. 1; and Fig. 5 is a transverse section on the dotted lines C D, Fig. 1. Fig. (5 is a back elevation of the coin-lever and partition of an inclosing-casing wheret-hrough the spout of the coin-slit passes. This view is shown specially for the purpose of representing the back of the pushing-in lever, so that a coin or the lever must be pushed absolutely home before it can again be withdrawn, as the pawl, which is a springarm working upon the rack upon one side and a plain part on the other side, has to travel from front to back and in a circular manner in order that the lever may be pushed in for pressing the coins home and pulled out the gas-outlet being shown in section and in a closed position.

The same letters of reference indicate correspondingpartsin allthe figures of the drawings. Y

a, is the gas-meter. a2 is a coin-slit, and as is the guide of the spout, (seen in the back elevation, Fig. 6,) and through which slit and down the said spout the coin falls and rests upon the short arm h2 of a coin-lever b,whose long arm b6 is weighted or counterpoised.` The said lever is best shown in back elevation in Fig. 6. The short arm of this said lever, which is made up of sides, with a division or space between them,carries a grooved pulley b', and situated at a distance from the said pulley is a second grooved pulley b, turning upon apin iitted within the iixed framing. Thus the pulley b4 may be spoken of as a Iixed pulley, and the pulley b as a movable pulley, and between these said pulleys the coin deposited in prepayment of gas to be consumed rests beforeit is pressed home,

carried upon the front face ofa penny measuring-out disk h, whose peripheryis provided with a notch or inclined gap h2, wherein the tooth or catch e engages. This tooth or catch iscarried upon the underside of the long arm e3 of a weighted lever e2, whose fulcrum center is the cross-axis b3 of the coin-lever b and slotted arm 002, and jointedly connected to the long arm of the said lever e2 is a forked upright l link e4, jointed at its upper end by pins e5, which connect it to the valve stem or stalk 1.02, by means of which the valve is opened and closed.

The pin f4, which is carried by the main lever f3, is made adjustable and ixed within the slot f6 by a screw-nut f7, so that by increasing the distance between the main-lever fulcrum f 5 .and the pin which controls the motion of a slotted arm :I: varyingY adjustments may be obtained. Thus, if the pin f4 be placed in the slot nearer to the fulcruin center f5, then the throw of the slotted arm will be less, and the movement required to be made by the rocking coin-lever b willualso be reduced, l

It will be seen that by the pushing inward of a coin c between the movable and adjustable rollers b b4 the short end b2 of the rooking coin-lever b is lowered, which on the turning of its fulcrum center b3 gives the same motion to the slotted arm and in consequence of the pin f4 being carried by the main lever f3, whose fulcrum center is at f5, the said pin moves up the slot2, and consequent thereby the mai11-lever long arm f3 and swinging pawl f are depressed, taking the hooked end f2 of the said swinging pawl at the back ot' the half-round snug 1% of a crank-lever 1, fulcrumed at 1b, and having the end lc weighted, and being kept in a determined position bya ixed stud or stop 1d. z

The hooked end f2 of the swingingpawl f has a pin f8, which traverses the convex of the snug l, and then on the upward movefinent it comes on the front of the snug and passes upon the inner and flat side of the said snug, thereby keeping the hooked end always up to 'the teeth 'of the ratchet-wheel during the time that the ratchet-wheel is being advanced, and on the further rising of the said swinging pawl the swell ff upon its inner edge comes against the axis p4 of the Shilling-nger-transmitting wheel and pulls the hooked end f2 from the teeth of the said ratchet-wheel. Thus by the oscillation of the main lever f3 the pin f8 of pawlfis made to travel around a snug, which, when it is upon its front side, keeps the hooked end of the pawl f up to its work, whichy is then drawn away by the swell, as aforesaid, as it will be observed that the down movement prevents the hooked end from wiping over the teeth, as is common with ordinary pawls, and,.fur ther, the said pawl is provided inward witha flat spring flo. The downward movement of IOO IIO

the main lever distends a coiled spring 2,dis

posed near itsjoint end and the top of the inclosing-casing. j

The rear end of the main lever f3 carriesa rack 3, which engages with a pinion 3f on an axis 3b, which has fast upon it a toothed wheel 3, which gears with a pinion 4b, whose axis carries a iiy 4, which by its rapid rotation encounters the resistance of the air, Vand so prevents the return of the moving parts too precpitously.

d is a lever fulcrumed at d3 for pushingin` ward a coin-pusher d2, whose inner end d4 impinges upon the periphery of a coin. The upright inner face of the said lever d covers up the coin-slit a2 and prevents the introduction of moneys until the pusher-arm has been wholly withdrawn, so as to admit of the coin tendered in payment of the quantity of gas required to be properly directed tothe top of L the grooved pulleys, as aforesaid. The back of the pusher-arm d2 is provided with a rack-and-pawl device for preventing the lever from being pulled back or the pusher-arm withdrawn until the coin has been pushed or forced fully home-that is, the lever and the pusher-arm must make their allotted inward motion before they can be withdrawn o1` pulled back, and which is done by making the spring-pawl, which is nothing more than a catch, traverse both the toothed and plain side of a rack in a circular manner.

d5 is a box-rack with teeth ZS upon its one side and plain upon its inner side d, as best seen in Figs. G, 7, and S. The top d10 of the said inner side is inclined inward.

d6 is a spring-pawlwith returned or hooked end dl, and when in its acting position its tendency is to spring outward, but not sufciently far to interfere with its properly wiping over the teeth of the rack. Thus when the lever d is pushed inward for the pressing home of the coin the arm (Z2 causes the teeth tls to be moved past and under the returned end d7 of the spring-pawl d unt-il it arrives past the top tooth, when it falls and springs inward to a little inward of the incline d10, when the outward movement of the lever now brings the pawl at the back (Z9, and in consequence of it traveling up the incline d10 ithas been bent inward, and on arriving at the gap (112 it resumes its normal condition and springs outward, with its under side resting at the bottom of the ineline of the bottoni tooth, so that by the pushing in and drawing out of the lever the hooked end is brought and made to travel up the inclines of the teeth, click over the shoulders, and each incline bends the pawl outward, so that on coming at the top of the incline ot' the top tooth it springs inwardly through the gap d to the commencement of the incline atthe back, and which incline on being drawn forward with the rack bends the spring-pawl inward until it has again come to the gap du and completed its circular movement. The cross-section of the end (Z7 of the spring-pawl d is shown at Fig. 9.

It will be observed. in referring back to the lever c? of the tooth or catch e, and by whose upward motion the valve-stalk zu is raised and lowered, that it is simply an arm loosely turning upon the axis b3 as a joint center, and is raised simply by the incline of the notches h2 and o3, the latter hereinafter described. On the advance movement made by the gasmeasuring-out disks 7L and 0 consequent upon the pulling round of the ratchet-wheel, the tooth or cat-ch e is removed from the notches onto the peripheries of the disks, respectively, and on the said disks moving backward to their allot-ted cubic metric distances the said tooth or catch falls again within the coincident notches, lowers the valve-stalk by the pulling down of the upright e, and so shuts off the gas or closes the valve, which is carried at the summit of the stalk.

The penny measuring-out disk 7z,which has upon its face the ratchet-wheel g, is tightl upon the arbor t, whose outer end 2 is reduced and carries the penny-indicating finger t3, whose rot-ation is made in front of the dial i5, so that the said wheels g 7i and arbor with finger at its end move together, and so does the rear part of the said arbor t4, which has a pinion n fast upon it, which engages with a toothed wheel. 1r", as best seen in the plan, Figs. Ll and 5, which communicates the motion of the finger-axis to the Shilling-disk 0, loosely ruiming upon the axis fil, and which Shilling-disk has a toothed wheel o2 fast upon its back, and which said motion to the shilling-disk and Aits finger p is communicated from the pinion n on penny-disk arbor to a toothed wheel p? and spindle p4, carrying pinions pg p6. The pinion p transmits the motion of the spindle jp* to the wheel o2 at the back of the Shilling-disk o, and so gives to the Shilling-disk on e hundred and forty-fourth of a revolution to every one-twelfth of a revotion made by the penny-disk 7L. Motion to the shillin g-Iin ger p made through the large loosely mounted toothed wheel p2, whose outer end has a sleeve upon which the said linger is carried.

lVorking loosely upon the arbor t' is a tangential or toothed meter-wheel q, driven from a worm m2 of a meter-axis m, and which said axis receives its mot-ion direct from the meterdrum.

Disposed between the inner end of the sleeve q2 of the meter-wheel qand the ratchetwheel g is a friction-clutch (2, by means of which mot-ion from the meter is transmitted to the penny and shilling measuring-out disks for taking them back through their measuredout and allotted distances, through which they have been moved forward, and which distances represent a iiXed quantity of gas which is allowed to be consumed in exchange for the coin passed through the machine. The clutch consists of a dished disk of metal with radially-directed slit edges, so as to create sufficient binding for the moving together or in common with another the parts in juxtaposition to its two opposite faces. Thus the function ofthe clutch is to create sutiicient binding-powerbetween the face of the ratchetwheel g and the meter-wheel q, that after the measuring-out disks have been advanced measured distances equivalent to the amount of gas paid for then the said disks and drivenwheels of the meter part move together proportional to the drums motion. Thus the pulling up of the swinging-pawl fand the advancing of the ratchet-wheel g through a measured distance the meterwheel q remains quiescent, as it cannot rotate in a reverse direction to the motion of the meterdrum, as it is pulling against the worm m2, so that the friction of the clutch makes fast the measuring-out part of the mechanism when it is to move in the same direction as and with the drum of the meter.

The action 0f the said automatic sale and delivery gas mechanism is as follows: On a ICO IIO

pennybeing passed through the coin-slit d2, when the lever d and pusher-arm d2 are pulled back, the coin falls by its own weight into position between iixed and movable rollers b b4, and when in this position, as represented in Figs. l and 6, the lever d is forcibly pushed inwardly, when the extreme end d4 of the pusher-arm cl2 impinges upon the rim of the coin and forces the said coin between the rollers b b4, which act or forcing inward of the said coin depresses the short arm h2, and roller b of the coin-lever?? raises the weighted end be', and also turns its axis b3 and with it the slotted arm whereby, through the intervention of the pin f 4, working within the slot m2, the main lever f3 is lowered upon its fulcrum center f5, depressing the swinging pawl, and with the pin f8 at the hooked end f2 made to pass around the outside of thev snug l at the top of the arm l of the weighted cranked lever, which is fulcrumed at lb, and on the said pin f8 arriving at the bottom of the said sn ug the pressure of the said spring f10 takes the point of the hooked end, as aforesaid, into a tooth of the ratchetwheel g, and when in this position, the coin having been forcibly pressed completely home,

or inwardly from between the rollers, the spring 2, which became distended on the lowering of the arm-lever, now contracts itself, drawing upward the main lever f3, and with it the swinging pawl f,which, bein g engaged With the tooth of the ratchet-wheel g, advances the ratchet-wheel to the extent of six teeth and with it the penny measuring-out disk 71, and Shilling measuring-out disk o through a distance of the one equal to one-twelfth of a revolution, and with the other through one hundred an d forty-fourth of a revolution. The upward movement of the hooked end f2 causes the pin fs to travel up inside of the snug l, and by the cran k-lever being weighted the tooth thereby is constantly kept up to the face of the ratchet-wheel until it arrives above the top of the snug, when it is drawn from it by the swell f9 being drawn against the axis p, which brings the pin fs to the top ofthe front side of the said snug ready for the next downward movement. The advancing forward of the penny measuring-out disk and the Shilling-disk causes the point of the tooth or catch e, which acts in common to both disks, to be withdrawn up the inclines of the notches or depressions h2o3 to the peripheries or edges of the disks, thus raising the tooth or catch lever e2 upon its fulcrum or hanging center, and in consequence of its outer end being raised .from a lower to a higher level by the lforcible displacement of the tooth from the notches the forked upright link e4 is consequently also raised, and the valve surmounting the valve-stalk @u2 is opened, thereby admitting gas to flow from the meter-pipe to the Service-pipe untilthenotches of the measuring, out disks have returned to their normal and coincident positions and opposite the tooth e. The parts which have resumed their normal fin ger 013 through a graduated distance in front of the dial, while the shilling-iinger p and disk o are turned through corresponding reduced distances by the pinion n engaging with the toothed wheel p5 to the spindle p4, and from thence through the pinions psp to the toothed wheel o2 of the disk o and the toothed wheel p2 of the sleeve of the finger p. The advance movements of the disks are made in a direction contrary to the motion of the meterdrum, and as the force applied is greater than the pressure of the clutch, the ratchet-wheel g and measuring out wheel h are moved through their allotted distances. The meterdrum, now moving, communicates its motion to the train of wheels, and through the clutch g2 to the measuring-out wheels, carrying the said wheels back to their normal positions until the catch or tooth e of thecatch-lever c2 comes opposite the notches h2 o3, when the said catch, moving slowly down the inclines, gradually shuts off the gas by the lowering of the lever, upright link e, valve-stalk wz, and valve, thereby cutting off communication between the pipe leading from the meter to the service-pipe. v

Fig. 14 shows a modified form of ,my invention. d is the meter, a2 the coin-slit, and a4 the front casing, wherein the main portion of the automatic sale Aand delivery mechanism is inclosed. a5 is the back compartment, wherein the coin-lever b Worksfof which b2 is the short arm, carrying a grooved pulley b', and which lever turns with its fulcrum b?, whose front end carries an arm f3 with its outer end provided with a swinging pawl f, whose lower hooked end f2 engages with the teeth of a ratchetwheel g upon the front face of a measuring-out disk h, having a notch h2 in its periphery. The swinging pawl f is pressed up to the teeth of the ratchet-wheel by a spring flo, while connection between the meter-going wheels is made by theclutch g', and motion received thereby through the wheel q, which is driven from the worm m2 of anr axis fm, with which the axis of the meter is in direct communication. c is the tooth or catch which engages with both the penny and the shilling measuring-out disk, and which is carried by a weighted and hanging lever e2, fulcrumed and turning upon the pin b3. w is a valve worked by a valve-stalk wz, jointedly connected at its lower end to the lever e2 and which stalk passes through a packing m5 situated within a gland a6 on the under side of the outlet u, leading from the met-er, and by the raising of which said valve, gas is allowed to pass to the service-pipe o. d is the le- IOO IIO

ver, and (l2 the pusher-arm, while b is the fixed pulley.

It will be thus seen that the arrangement Figs. ll is only a simplified t'orm of the arrangements Figs. 1,2, and 3. Thus on placing a penny through the slit a2 it drops'upon the grooved pulleys b b", and on the pressing inward of the pusher-arm d2 of the lever d the coin is forced home between the rollers, which depresses the short arm b2 of the lever l), turns its joint center b3, and with it raises the lever f5 and pawl f, whose hooked end f2 engages with the teeth of the ratchet-wheel, pulling it round to the extent of siX teeth, and also advances or winds up the penny and Shilling measuring-out disks h and o, which causes the point of the tooth or catch c to travel up the inclines ot' the notches h2 03 (the latter not shown) until the said tooth or catch .rests upon the peripheries of the said disks, which change ot elevation raises the lever e2, valve-stalk wg and valve ir, thus allowing to pass from the gas-meter outlet u to the service-pipe lU,and as the whole of the other parts of the automatic sale and delivery mechanism are alike those of Figs. 3 to 13 the re-rotation of the measuring-out disks on the penny worth of gas being consumed brings the notches opposite the tooth or catch e, when by the change of elevation from the rims to the bottoms of the notches the valve lowered by the falling of the valve-stalk.
